50p you so much : )
you will start with four different numbers between 1 to 10. combine these integers, using each number once, to make an expression equal to 1. then repeat, using each number once, to make an expression equal to 2, and so on. you'll use the four numbers to make expressions equal to the numbers 1-10, and each expression you make is worth 1 point. for example, say you are given 1, 2, 3, and 4, you could create the following expressions:
1 = (2 – 1) • (4 - 3) 6 = 12 ÷ 4 + 3
2 = (2 • 1) • (4 - 3) 7 = 13 – 4 – 2
3 = 4 – 3 ÷ (2 + 1) 8 = 12 ÷ 3 + 4
4 = 1 + 2 + 4 – 3 9 = 14 – 3 – 2
5 = 32 – 41 10 = 14 ÷ 2 + 3
you can combine your numbers to make two- or three-digit numbers. for example, see the expressions above for 6-10.
you can use parentheses, and you can even have nested parentheses.
you can use exponents.
if you use division, the integers should be evenly divisible. for example, 4 ÷ 2 is okay, but 3 ÷ 2 is not okay.
when you turn in your solution to this problem, make sure that you write down the four numbers that you started with. you may choose any of the following sets of four numbers for this problem:
1, 4, 6, and 8
3, 3, 4, and 5
4, 6, 7, and 8
2, 4, 6, and 8
